SUMMARY OF THE INVENTION

1. Field of the Invention

The present invention relates to a timepiece equipped with a displaycorrection device constituted to be capable of correcting a displaycontent displayed by display members of an hour hand, a minute hand, adate indicator, a day indicator and the like by rotating a winding stem.

Further, the invention relates to a correction device for a timepiecefor correcting the display content by rotating the winding stem.

2. Background Information

According to a timepiece equipped with a display correction device,there has been used a rocking yoke provided at a main plate which isrockable to three positions by operating a setting lever. A settingwheel is rotatably provided to a rocking yoke. A calendar correctionrocking lever is rockably provided to the rocking yoke. A calendarcorrector setting wheel is rotatably provided to the calendar correctionrocking lever and is arranged to be capable of slipping by constant sliptorque.

When a winding stem exists at the 0-th stage, the rocking yoke ispositioned at a first position in the axis line direction of the windingstem, and when the winding stem is rotated, a sliding pinion is rotatedand the setting wheel and the calendar corrector setting wheel arerotated based on rotation of the sliding pinion. Under this state, thereis no gear rotating based on rotation of the calendar corrector settingwheel.

When the winding stem is drawn to the first stage, the rocking yoke isrotated based on rotation of a setting lever. Then, the rocking yoke ispositioned at a second position in the axis line direction of thewinding stem. When the winding stem is rotated, the sliding pinion isrotated and the setting wheel and the calendar corrector setting wheelare rotated based on rotation of the sliding pinion. When the windingstem is rotated to the right, the calendar corrector rocking lever isrocked in a first direction, based on rotation of the calendar correctorsetting wheel, a day indicator is rotated and day correction is carriedout. When the winding stem is rotated to the left, the calendarcorrector rocking lever is rocked in a second direction reverse to thefirst direction and based on the rotation of the calendar correctorsetting wheel, a day corrector setting wheel is rotated. Based onrotation of the day corrector setting wheel, the day wheel is rotatedand day correction is carried out.

When the winding stem is drawn to the second stage, based on rotation ofthe setting lever, the rocking yoke is rotated. Then, the rocking yokeis positioned to a second position in the axis line direction of thewinding stem. When the winding stem is rotated, the sliding pinion isrotated and based on rotation of the sliding pinion, the setting wheeland the calendar corrector setting wheel are rotated. Under this state,there is no gear rotating based on the rotation of the calendarcorrector setting wheel. When the winding stem is rotated, based onrotation of the setting wheel, a minute wheel is rotated. By rotatingthe minute wheel, a minute driving wheel and an hour wheel are rotated.Therefore, based on the rotation of the winding stem, display of aminute hand attached to the minute driving wheel and an hour handattached to the hour wheel can be corrected.

According to such a conventional structure, the sliding pinion isconstituted to move to three locations of the first position incorrespondence with the 0-th stage of the winding stem, the secondposition in correspondence with the first stage of the winding stem andthe third position in correspondence with the second stage of thewinding stem. Further, the setting wheel, the calendar correctionrocking lever and the calendar corrector setting wheel are attached tothe rocking yoke.

However, according to the conventional timepiece equipped with a displaycorrection device, the following problems are posed.

(1) When the winding stem is rotated and display of the date indicatorand the day indicator is corrected to thereby correct time, the slidingpinion is moved to the three locations of the positions in therotational axis line of the winding stem and accordingly, an amount ofmoving the sliding pinion is large. Therefore, a dimension of a movementof a timepiece with regard to the axis line direction of the windingstem becomes large.

(2) There is used the rocking yoke mounted with a plurality of parts andaccordingly, shapes of parts constituting the display correction deviceare complicated and a large period of time is required in fabrication ofthe parts and assembly of the timepiece.

Hence, in order to resolve such conventional problems, objects of theinvention reside in points described below.

(1) A movement of a timepiece equipped with a display correction deviceis to be downsized by realizing a display correction device in which anamount of moving a sliding pinion in an axis line direction of a windingstem is small.

(2) A timepiece equipped with a display correction device in whichfabrication and assembly are facilitated is to be realized bysimplifying shapes of parts constituting the display correction device.

(3-1) Operation of date correction:

In reference to FIG. 4 through FIG. 6, the winding stem 110 is drawn byone stage from the state in which the winding stem 110 is disposed atthe 0-th stage to the state in which the winding stem 110 is disposed atthe first stage. When the winding stem 110 is drawn by one stage, thesetting lever 120 is rotated in the counterclockwise direction and theyoke 122 is rotated in the clockwise direction. Under the state, the Atooth 122 a of the sliding pinion 114 is in mesh with the setting wheel128 and the B tooth 122 b of the sliding pinion 114 is not in mesh withthe winding pinion 116.

When the winding stem 110 is disposed at the first stage, as describedabove, the train wheel stop lever 170 is rotated in the clockwisedirection by the setting lever 170 and the rocking bar contact portion170 a of the train wheel stop lever 170 is positioned by being broughtinto contact with the first correction transfer wheel shaft portion 132a. By the operation of the train wheel stop lever 170, the rocking bar130 is rotated in the counterclockwise direction and the secondcorrection transfer wheel shaft portion 134 a is brought into contactwith a cylindrical wall face of the rocking bar positioning hole 102 fproximate to the 9 o'clock side. Under the state, the train wheel stoplever 170 is not brought into contact with the balance with hairspring210.

When the winding stem 110 is rotated to the right (when the winding stem110 is rotated in the clockwise direction in view from the outer side ofthe timepiece), based on rotation of the sliding pinion 114, the settingwheel 128 is rotated in the counterclockwise direction. Based onrotation of the setting wheel 128, the first correction transfer wheel132 is rotated in the clockwise direction. Based on rotation of thefirst correction transfer wheel 132, the second correction transferwheel 134 is rotated in the counterclockwise direction. Based onrotation of the second correction transfer wheel 134, the thirdcorrection transfer wheel 140 is rotated in the clockwise direction.Then, the rocking lever 142 is rotated in the clockwise direction andthe corrector setting wheel shaft portion 144 c is positioned by beingbrought into contact with a cylindrical wall face of the rocking leverpositioning hole 102 g on a side proximate to the 3 o'clock side. Underthe state, when the winding stem 110 is rotated to the right, the thirdcorrection transfer wheel 140 can be made to slip against the rockinglever 142.

Based on rotation of the third correction transfer wheel 140, thecorrector setting wheel 144 is rotated in the counterclockwise directionat a position shown by FIG. 4. Based on such rotation of a correctorsetting gear 144 b, the date wheel 150 is rotated in thecounterclockwise direction. The position in the rotational direction ofthe date indicator 150 is determined by a date jumper 180.

As has been explained, according to the timepiece of the invention, byrotating the hand setting lever 110 to the right in the state in whichthe winding stem 110 is disposed at the first stage, date correction canbe carried out.

(3-2) Operation of day correction

In reference to FIG. 6 through FIG. 8, when the winding stem 110 isrotated to the left (when the winding stem 110 is rotated in thecounterclockwise direction in view from the outer side of the timepiece)in the state in which the winding stem 110 is disposed at the firststage, based on the rotation of the sliding pinion 114, the settingwheel 118 is rotated in the clockwise direction. Based on rotation ofthe setting wheel 128, the first correction transfer wheel 132 isrotated in the counterclockwise direction. Based on rotation of thefirst correction transfer wheel 132, the second correction transferwheel 134 is rotated in the clockwise direction. Based on rotation ofthe second correction transfer wheel 134, the third correction transferwheel is rotated in the counterclockwise direction. Then, the rockinglever 142 is rotated in the counterclockwise direction and the correctorsetting wheel shaft portion 144 c is positioned by being brought intocontact with the cylindrical wall face of the rocking lever positioninghole 102 g on a side proximate to the 9 o'clock side. Under the state,when the winding stem 110 is rotated to the left, the third correctiontransfer wheel 140 can be made to slip against the rocking lever 142.

Based on rotation of the third correction transfer wheel 140, thecorrector setting wheel 144 is rotated in the clockwise direction at aposition shown by FIG. 7. Based on such rotation of the correctorsetting gear 144 b, the day corrector setting wheel 158 is rotated inthe counterclockwise direction. Then, based on rotation of the daycorrector setting wheel 158, the day indicator 152 is rotated in theclockwise direction. The position in the rotational direction of the dayindicator 150 is determined by a day jumper 182.

As has been explained, in the case of the timepiece equipped with thedisplay correction device according to the invention, by rotating thewinding stem 110 to the left in the state in which the winding stem 110is disposed at the first stage, day correction can be carried out.

In reference to FIG. 8, the date feeding mechanism of the timepieceequipped with the display correction device according to the invention,includes a date indicator driving wheel 252 rotated by one rotation in24 hours based on rotation of an hour wheel 250 rotated by one rotationin 12 hours and a date indicator driving finger 254.

Further, the day feed mechanism of the timepiece equipped with thedisplay correction device according to the invention, includes a dayindicator driving finger 258 for feeding the date indicator 152 by 2teeth per day based on rotation of the date indicator driving wheel 252.The day indicator 152 is rotatably supported relative to the hour wheel250 by a day indicator holding spacer 162.

(4) Structure and operation of the first embodiment of the timepieceequipped with the display correction device according to the inventionunder the state in which the winding stem is disposed at the secondstage.

In reference to FIG. 9 through FIG. 11, the winding stem 110 is drawn byfurther one stage from the first stage to thereby bring about the statein which the winding stem 110 is disposed at the second stage. When thewinding stem 110 is drawn by further one stage, the setting lever 120 isrotated further in the counterclockwise direction. In this operation,the yoke 122 is not rotated. Therefore, in the state in which thewinding stem 110 is disposed at the second stage, similar to the statein which the winding stem 110 is disposed at the first stage, the Atooth 122 a of the sliding pinion 114 stays to be in mesh with thesetting wheel 128 and the B tooth 122 b of the sliding pinion 114 is notin mesh with the winding pinion 116.

When the winding stem 110 is disposed at the second stage, by rotatingthe setting lever 120, the train wheel stop lever 170 is rotated in thecounterclockwise direction, the train wheel stop operating portion 170 fof the train wheel stop lever 170 is brought into contact with an outerperiphery of a portion of a balance of the balance with hairspring 210to thereby stop rotation of the balance with hairspring 210. As aresult, a pallet fork 268 and an escape wheel & pinion 262 are notoperated, rotation of the second indicator 264 is restrained androtation of the second hand 266 is stopped.

The train wheel stop operating portion 170 f of the train wheel stoplever 170 may be constituted by an end face of the train wheel stoplever 170 or may be constituted by orthogonally bending the end face ofthe train wheel stop lever 170 or may be constituted by fixing aseparate pin for stopping train wheel at the end portion of the trainwheel stop lever 170.

Further, by rotating the setting lever 120, a setting lever positioningpin 120 b pushes the setting lever engaging portion 130 e of the rockingbar 130. Then, the rocking bar 130 is rotated in the clockwise directionand the second correction transfer wheel shaft portion 134 a is broughtinto contact with the cylindrical wall face of the rocking barpositioning hole 102 f on a side proximate to the 3 o'clock side. Then,the second intermediate minute wheel 162 is in mesh with the minutewheel 166.

When the winding stem 110 is rotated to the right (when the winding stem110 is rotated in the clockwise direction in view from the outer side ofthe timepiece), based on rotation of the sliding pinion 128, the firstintermediate minute wheel 160 is rotated in the clockwise direction.Based on rotation of the first intermediate minute wheel 160, the secondintermediate minute wheel 162 is rotated in the counterclockwisedirection. Based on rotation of the second intermediate minute wheel162, the minute wheel 166 is rotated in the clockwise direction. Basedon rotation of the minute wheel 166, the hour wheel 250 and the minutedriving wheel 260 are rotated in the counterclockwise direction.Therefore, when the winding stem 110 is disposed at the second stage, byrotating the winding stem 110 to the right, so-to-speak “inverse handsetting” can be carried out.

In contrast thereto, when the winding stem 110 is rotated to the left(when the winding stem 110 is rotated in the counterclockwise directionin view from the outer side of the timepiece), based on rotation of thesliding pinion 114, the setting wheel 128 is rotated in the clockwisedirection. Based on rotation of the setting wheel 128, the firstintermediate minute wheel 160 is rotated in the counterclockwisedirection. Based on rotation of the first intermediate minute wheel 160,the second intermediate minute wheel 162 is rotated in the clockwisedirection. Based on rotation of the second intermediate minute wheel162, the minute wheel 166 is rotated in the counterclockwise direction.Based on rotation of the minute wheel 166, the hour wheel 250 and theminute driving wheel 260 are rotated in the clockwise direction.Therefore, when the winding stem 110 is disposed at the second stage, byrotating the winding stem 110 to the left, so-to-speak “regular handsetting” can be carried out.

By rotating the hour wheel 250, display content of “o'clock” which thehour hand 256 attached to the hour wheel 250 displays can be corrected.By rotating the minute driving wheel 270, display content of “minute”which the minute hand 276 attached to the minute driving wheel 270displays can be corrected. Further, by operation of the train wheel stoplever 170, in a time period in which display content of “o'clock” and“minute” are being corrected, display content of “second” is notchanged.

In reference to FIG. 16, a movement 400 of a second embodiment of atimepiece equipped with a display correction device according to theinvention is constituted by an analog electronic timepiece.

A point of the movement 400 of the second embodiment of the timepieceequipped with a display correction device according to the inventionwhich differs from the movement 100 of the first embodiment of thetimepiece equipped with the display correction device according to theinvention, resides in the structure on the front side, that is,constitutions of a power source, a control device for controllingrotational speed of train wheel and front train wheel of the timepiece.

That is, a switch device, a back train wheel, a hand setting device, adate feed device, a day feed device, a date correction device and a daycorrection device are similar to those in the structure of the movement100. Therefore, with regard to FIG. 16, an explanation of portionssimilar to those in the structure shown by FIG. 1 will be omitted.

A train wheel stop wheel 292 is arranged on the front side of themovement 400. The train wheel stop wheel 292 is in mesh with the secondwheel 264 or a fourth wheel & pinion 290. In the case in which themovement 400 is a timepiece having a “small second hand”, it ispreferable that the train wheel stop wheel 294 is constituted to be inmesh with the second wheel 264. In the case in which the movement 400 isa timepiece having “center three hands”, it is preferable that the trainwheel stop wheel 292 is constituted to be in mesh with the fourth wheel& pinion 290.

The train wheel stop lever 170 is constituted to restrain the trainwheel stop wheel 292 when the train wheel stop lever 170 is operated.

The rotational center of the train wheel stop wheel 292 is arranged at aregion of a half of the first region of the movement remote from thewinding stem 110 (referred to as “9 through 12 o'clock region” incorrespondence with numerals of the dial). Particularly, it ispreferable that the rotational center of the train wheel stop wheel 292is arranged between the “10 o'clock direction” and the “11 o'clockdirection” of the movement.

(7) Structure of a third embodiment of a timepiece equipped with adisplay correction device according to the invention.

In reference to FIG. 17, a movement 500 of a third embodiment of atimepiece equipped with a display correction device according to theinvention is constituted by an analog electronic timepiece.

A point of the movement 500 of the third embodiment of the timepieceequipped with a display correction apparatus according to the inventionwhich differs from the movement 400 of the second embodiment of thetimepiece equipped with the display correction device according to theinvention, resides in that arrangement of parts on the front side andarrangement of parts on the back side are arranged in symmetry (mirrorsymmetry) with regard to the reference axis line 112.

Therefore, the rotational center of the train wheel stop wheel 292 isarranged at a region of a half of the second region of the movementremote from the winding stem 110 (referred to as “6 through 9 o'clockregion” in correspondence with numerals of the dial). Particularly, itis preferable that the rotational center of the train wheel stop wheel292 is arranged between the “7 o'clock direction” and the “8 o'clockdirection” of the movement.

Although not particularly illustrated, also in the case in which atimepiece equipped with a display correction device according to theinvention is constituted by a mechanical type timepiece, parts shown byFIG. 12 through FIG. 14 can be arranged in left and right symmetry(mirror symmetry) with regard to the reference axis line 112.

(8) Operation of second embodiment of a timepiece equipped with adisplay correction device according to the invention.

An explanation will be given of operation of a display correction deviceof the second embodiment of the timepiece equipped with the displaycorrection device according to the invention.

Operation of a display correction device of the third embodiment of thetimepiece equipped with the display correction device according to theinvention, is substantially similar to operation of the displaycorrection device of the second embodiment and accordingly, a detailedexplanation thereof will be omitted here.

The movement 400 of the timepiece equipped with the display correctiondevice according to the invention is not provided with a winding pinionand a winding device. When the winding stem 110 is disposed at the 0-thstage, there is no gear in mesh with the sliding pinion 114. It is notnecessary to provide a B tooth to the sliding pinion 114.

According to the movement 400, in the state in which the winding stem110 is disposed at the 0-th stage, when the winding stem 110 is rotated,only the sliding pinion 114 is rotated.

Operation in the state in which the winding stem 110 is disposed at thefirst stage, is similar to operation of the first embodiment of thetimepiece equipped with the display correction device according to theinvention.

In reference to FIG. 18, in the state in which the winding stem 110 isdisposed at the first stage, the A tooth 122 a of the sliding pinion 114stays to be in mesh with the setting wheel 128.

By rotating the setting lever 120, the train wheel stop lever 170 isrotated in the counterclockwise direction and the train wheel stopoperating portion 170 f of the train wheel stop lever 170 is broughtinto contact with the train wheel stop wheel 292 and stops rotation ofthe train wheel stop wheel 292. As a result, rotation of the fourthwheel & pinion 290 in mesh with the train wheel stop wheel 292 isrestrained and rotation of the second hand 266 is stopped.

A gear restrained by the train wheel stop lever 170 may be the trainwheel stop wheel 292 in mesh with the fourth wheel & pinion 290 or maybe the fourth wheel & pinion 290. Further, as shown by FIG. 19, in thecase of a timepiece in which the fourth wheel & pinion 290 and a fifthwheel & pinion 170 are provided and the second wheel 266 is attached tothe fourth wheel & pinion 290, the fourth wheel & pinion 290 may berestrained or the fifth wheel & pinion 170 may be restrained.

According to the movement 400, operation of the rocking bar 130 byrotation of the setting lever 120 and operation of the setting wheel128, the first intermediate minute wheel 160 and the second intermediateminute wheel 162 by rotation of the winding stem 110 are similar tothose of the operation of the first embodiment of the timepiece equippedwith the display correction device according to the invention.

Therefore, when the winding stem 110 is disposed at the second stage, byrotating the winding stem 110 to the right, so-to-speak “reverse handsetting” can be carried out and by rotating the winding stem 110 to theleft, so-to-speak “regular hand setting” can be carried out.

A similar explanation is applicable also to the movement 500 shown byFIG. 17.
